Introduction
The L5514 modem enables the user to communicate with the
LINK
control system containing
LINK 2
hardware from a
remote location using the Eurotherm Drives
LINK
Tool ConfigEd V5.x or DSD installed on a computer with an internal or
external modem. Users can perform virtually all
LINK
commands over the telephone line to troubleshoot, upgrade, adjust,
and monitor parameters.
The L5514 kit consists of a high speed modem, a DB-9 to RJ-11 converter, a modem serial cable, and a telephone line
cable.
Mounting
The L5514 modem can be mounted on any standard DIN rail. Mounted dimensions (2.92”)H x (4.75”)W x (1.35”)D.
Connections and Setup
1. Connect the telephone cable from the telephone wall jack to the line phone connector on the modem. (No PBX)
2. Connect the DB-9 to RJ-11 converter to the RS-232 connector on the top of the modem and plug in the modem serial
cable (Large connector to the converter, small connector to the
LINK 2
series hardware).
3. Connect ground to terminal #1, +24Vdc (from regulated power supply) to terminal #2, and 0v common to terminal #3
on the power connector.
4. Turn on power to modem.
5. The modem has been preprogrammed and tested at the factory and will need no setup by the customer. If the modem
program is lost or changed, refer to the following section to reprogram the modem.
Modem String Command Definitions
&F = Recalls factory defaults
E = Disables echoing of the commands to the screen
M = Disables Modem speaker
Q1 = Disables result codes to be issued to the screen
K = Disables flow control
S0 = 1 auto answer set to pick up after 1 ring
&W0 =Saves as user profile 0
Factory preprogrammed initialization string = (AT &F E M Q1 &K S0=1 &W)
Note:
The
LINK2
RTNX communication port is fixed at 57.6kbaud. At power up the modem and the
LINK 2
module
need to be at the same baud rate. The initialization string must be sent to the modem at 57.6kbaud, so that the port speed of
57.6kbaud will be stored to the modem EEPROM.
Communication through the Modem
Once powered up the L5514
LINK
modem is ready to use. Users can now communicate to the remote network through the
L5514 using ConfigEd V5.x or DSD installed on a computer. Refer to the Configuration Editor Version 5 Software Manual
(RG353792) and the information provided with your personal computer for the local modem communication setup.
Note:
It is important to cycle (remove and then reapply) DC power to the modem each time the serial cable is disconnected
and then reconnected. The serial port of the modem may not function properly if the power is not cycled.
